Not now. Choose another Greer fishing window.
No access method is recommended today. Recheck the Greer flow, weather, and exact water before trying again. Do not use this score to plan a fork or lake trip.
Check first: Water temperature not verified; do not use this score to clear warm-water risk. Current Greer flow and weather support a mainstem planning estimate, not measured fishing quality. Water temperature, clarity, fish activity, and exact access conditions need local checks.
Rating updatedRiver local time:
USGS shows 21 cfs. The flow has been stable over about 6 hours. USGS marks this reading provisional and may revise it. USGS records for this date (1960-2025, 41 readings) show a median near 10 cfs and the upper quartile near 14 cfs; today's flow is high for the date. USGS 09383400 measures discharge and stage on the Greer mainstem above River Reservoir. It does not measure the forks, lakes, water temperature, clarity, fish activity, legal access, or safe wading. Historical flow percentiles are date-specific context, not universal fishable-flow limits. The same-date comparison uses 1960-2025 gauge records; use that older record as context, not a current normal-flow threshold. Fishable water may exist, but do not rate it highly without a safe access, clarity, and wading or boat plan.

This is an air forecast, not a river-temperature reading. Check the water with a stream thermometer before fishing in hot weather.

Latest reading: 21 cfs. Falling over about 6 hours. Chart covers Sep 5 through Sep 12; readings are provisional and may be revised.

Current U.S. Geological Survey gauge: Little Colorado River at Greer
Seasonal starting points, not a live hatch report. Match what you see on the water.
Pick the current month's row, then match the fly to observed feeding. Sizes are starting points, not a report of a hatch happening today.
Every fly below has a matching pictured guide. A dry-dropper is a rig: pair a buoyant dry with a light nymph only where the rules and casting space allow it.
Settling flows can make a short session easier to plan. Monsoon storms, cold nights, ice, and local water temperature can change that plan. Use the live evidence above and inspect your access.
Use USGS 09383400 discharge, observation time, and trend. Stage is height at the instrument, not depth at your crossing.
Check visibility, footing, depth, current, and a dry exit. Stay on land when you cannot assess them.
Carry a stream thermometer. Air temperature and high elevation do not prove trout-safe water. Stop at 70°F or warmer.
Leave for thunder or rapid rises. Do not use a favorable rating to cross swollen water or shelf ice.
No access method is recommended in today's conditions. Review the live river and weather checks before making another plan.
Not recommended today. Recheck the river, weather, and access before planning another trip.

This report does not recommend floating this reach.
Plan a short bank or walk-and-wade session on the Greer mainstem above River Reservoir. Check today's flow, forecast, and seasonal rules; the forks and lakes need separate plans.
USGS 09383400 measures discharge and stage at Greer. Today's rating combines that local flow context with weather and reviewed trout-planning assumptions. It does not measure water temperature, clarity, fish activity, or conditions at every bank.

USGS 09383400 at Greer has no current continuous water-temperature reading. Measure the stream at the exact access. Choose another water at 70°F or warmer.
The forecast has storm or heavy-precipitation risk, so timing and access matter more than the score alone.
September–October: Try smaller dries and nymphs when feeding supports them.
The current NWS air forecast is about 78F. Chance Showers And Thunderstorms.
Compare fresh USGS 09383400 flow with the six-hour trend and same-date history. No fixed cfs range guarantees fishing quality, clarity, or safe wading.
Skip or leave for lightning, rapid rises, ice, unsafe footing, uncertain access, or trout water at 70°F or warmer. A missing or stale gauge cannot support a current numeric rating.
Choose one legal Greer bank, check the flow and forecast, confirm seasonal rules, and inspect the water before rigging a small fly.
If this reach is unsuitable, choose another day or begin a separate conditions and rules check for another water. Do not assume a lake or fork is safer.
When: Year-round planning, with seasonal tackle and harvest rules
Use the main river rule below and current notices. Legal season, suitable water temperature, and actual fish activity are separate checks.

This main river score does not rate the forks or Greer Lakes. Check their own boundaries, rules, access, and water.
A road, bridge, trail, or gauge is not permission to cross private land. Confirm the exact bank and approach before leaving your vehicle.
Above River Reservoir to the East/West Fork confluence: October 1–April 30 is trout catch-and-release with artificial flies or lures only. General statewide rules apply May 1–September 30. The forks and lakes have separate rules. Check the current Arizona guide and emergency notices before fishing.

What was checked: Official sources support gauge identity, reach rules, access context, and weather. Fly choices are editorial suggestions. No field visit, current hatch, bite, stocking event, water temperature, clarity, access inspection, or safe-wading assessment is claimed.
Live measurements and forecasts keep their provider timestamps. Rules, access, and trip guidance use the source-review date shown here. BlueStreamFly planning advice is editorial interpretation, not an agency notice.
First-hand experience: BlueStreamFly does not claim a first-hand visit or local field test for this report unless a real contributor is explicitly named and linked.
Yes. USGS 09383400 supplies the Greer discharge and seven-day chart. It also reports stage, but not current water temperature, clarity, or safe depth at your access.
The Greer main river above River Reservoir to the East/West Fork confluence, using the local Greer gauge and weather. It is an editorial planning rating, not a fishing-success or wading-safety measurement.
No. The special main river catch-and-release and artificial-fly/lure window is October through April. General statewide rules apply May through September. Check the precise boundaries and current official rules before fishing.
This report does not recommend floating. Choose a legal bank or a protected-edge wading plan after checking current, depth, footing, temperature, and an easy exit.
Start with the pictured row for your month. Small Pheasant Tails and Zebra Midges cover subsurface options. Use caddis, mayfly dries, or terrestrials when you see corresponding activity. The table is planning guidance, not a live hatch report.
No. It has no current continuous water-temperature reading. Measure the stream at your access and stop trout fishing at 70°F or warmer. Stop sooner if fish show stress.
No. The East Fork, West Fork, South Fork, and lakes require their own conditions, rule, and access checks. A closure on a fork does not automatically close the rated main river.
